ESD Zero Resistance Low Pull Sear for Amoeba Striker Airsoft Sniper Rifles

"Just installed this unit. Very easy, bearings and pins fit perfectly. Trigger pull is crisp and consistent. I would highly recommend this if you are using a higher spring rate in your bolt. I'm using the CPSB SS bolt with a 550 FPS spring and so far everything is working great.

"Installation was pretty easy. Bearings seem to hold but can't really tell until I put thousands of rounds through her. I love the 1 piece design. Trigger is harder to pull but once it breaks, shot is instant. I'm used to my 45 degree vsr where it's a smoother trigger pull but longer travel. Can handle the m170 so far. I think the piston will break before this sear does. Must have upgrades for Amoeba As-01 Strikers are trigger sear and cylinder. AS-02 is fine with just the cylinder as both will pull lose from the bolt handle because the cylinder is made of painted brass.

"The actual sear, 10/10, looks solid. It might break down the road, but they sell the sear separately.
As for the bearings, I recommend you buy just the sear and find a replacement.
The bearings get a 1/10. Both of them broke within minutes of testing to ensure it worked properly.
They both were crushed by the stock spring; they're just too small and too precise to be strong enough to withstand the force.
If there were a replacement involving bushings, maybe it would be better, but now I'm looking to 3D print my own stronger replacements.
The question is whether or not it will work, but I might as well try.
(By the way, if you're all out of options, stack a bunch of shims together; it works... somehow.)
